Is there a way I can get replacement these

I'm missing one, and the best way to actually transport the thing is to package it back and I can't really do that because I only have one of the supporting thing on the sides.

I've never done that before.

I guess I could use the one I have and put packing peanuts or stuffed newspaper in the location of the other one
